APPARATUS FOR DRAWING LIQUIDS.

Specification of Letters Patent.

Patented Apr. 3, 1917.

Application filed January 15, 1916. Serial No. 72,286.

To all whom it may concern:

Be it known that I, MYRTLE E. CURL, a citizen of the United States, residing at Port Orford, in the county of Curry and State of Oregon, have invented certain new and useful Improvements in Apparatus for Drawing Liquids, of which the following is a specification.

This invention relates to apparatus for drawing liquid from barrels, tanks, and in fact, all classes of containers or storage ves sels and has as its primary object to provide means whereby such liquid may bedrawn ofi into bottles, jugs, metallic cans, and in fact, all types of receptacles or packages, without likelihood of wasting any of the liquid or overflowing the said receptacles.

Another aim of the invention is to so con struct the apparatus that a number of hottles or other receptacles may be quickly and conveniently filled and all with exactly the same quantity of the liquid.

Another object of the invention is to s0 construct the apparatus that the same will automatically operate to draw off the liquid when the receptacle to be filled is placed in position to receive the liquid.

Another aim of the invention is to so construct the apparatus that the parts comprising the same may be readily and quickly disassembled whenever desired and thoroughly sterilized and cleaned.

In the accompanying drawings:

Figure 1 is a vertical longitudinal sectional view through the apparatus embodying the present invention.

Fig. 2 is a perspective view of one mem ber of the apparatus.

Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 1.

Fig. 4 is a view similar to Fig. '1 illustrating a slightly modified form of the invention.

Fig. 5 is a view similar to Fig. 2 illustrating a portion of the modified structure shown in Fig. 4.

In that form of the invention shown in Figs. 1 to 3 inclusive, the apparatus embodies a discharge tube which is indicated by the'numeral 1 and is here illustrated as of uniform diameter throughout its length and either permanently or removably fitted in an opening 2 in a plug 3 which may be of cork, metal, or any other material suitable for the purpose, this plug being exteriorly tapered and being designed to be fitted, as shown in Fig. 1, in an opening 4: in the bottom of a barrel 5 or any other receptacle from which it is desired to drain a liquid. The discharge tube 1 extends below the plug 3 a suitable distance and in practice the length of this tube will be governed by the character and dimensions of the bottle or other receptacle to be filled. For example, if the apparatus is to be employed in filling bottles such as beer bottles of a uniform size, the tube will be of such length as to extend down into the neck of the bottle such distance that the lower or discharge end of the tube will be located substantially at the point at which it is desired the liquid level shall be when the bottle is properly filled so that when the liquid level reaches this point liquid will cease to flow from the tube into the bottle. Arranged within the discharge tube 1 is a vent tube indicated by the numeral 6 and this tube at its upper end is provided with a hollow flared head 7 having a closed upper end 8 and provided in its side with one or more openings 9. The lower end of the vent tube is open as clearly shown in Fig. 1 of the drawings. The vent tube 6 is of consider ably less diameter than the tube 1 as will be observed by reference to Fig. 1 but its head 7 is of such diameter adjacent its upper end that when the tube is lowered into the tube 1 the head 7 will seat snugly within the upper end of the said tube 1 and close the said end. In such position of the vent tube the opening 9 will be located below the plane of the upper end of the discharge tube 1 and consequently liquid will be prevented from flowing from the barrel 5 through the said tube 1. The manner in which the vent tube is to be lifted so that its head may clear the open end of the tube 1 in the manner of a valve and allow liquid to flow from the barrel through the discharge tube 1, will presently be fully explained.

The lifting device is assembled with the tube 6 and the same is preferably formed from a single length of wire bent to form spaced side portions 10 which at their lower ends are inclined inwardly toward each other as at 11 and are thence bent upwardly at an acute angle and in crossed relation as indicated at 12. The intermediate portion of the wire or, in other words, that portion integrally connecting the portions 12 is so bent as to form spaced side portions 13 and a transverse portion 14:. The wire is prefers ably resilient and by reference to Fig. 1 of the drawings it will be observed that the portions 18 snugly contact the inner surface of the bore of the tube 6 at the lower end of the said tube, the portions 13 and 14: constituting a head frictionally connecting the lifting member with the said tube 6. The upper ends of the side portions 10 are bent laterally in opposite directions preferably at right angles as indicated at 15 and thence back upon themselves as at 16 and thence vertically as at 17 and the portions 15 and 16 constitute lateral fingers which serve a purpose to be presently pointed out. The numeral 18 indicates a ring within which the terminals 17 project and are secured in any suitable manner as for example, by solder. It will now be apparentthat with the parts properly assembled the portions 10 of the lifting member will extend vertically beside opposite sides of the discharge tube 1 and that the fingers of the lifting member will project outwardly in opposite directions. When a bottle to be filled is fitted upwardly to the apparatus so that the tube 1 will extend down into the neck of the bottle as shown in Fig. 1 of the drawings and the bottle is moved upwardly the upper end of its neck will engage against the fingers of the lifting device and the said device will in the continued upward movement of the bottle lift the vent tube 6 moving the head 7 away from the upper end of the discharge tube 1 and allowing the liquid to flow from the barrel through the discharge tube and into the bottle. As the liquid leaves the barrel, air enters the barrel by passing upwardly through the vent tube 6 and out through the opening or openings 9. In practice the bottle will be moved upwardly until the ring 18 contacts the lower end of the plug 3 and the bottle will be held in this position until the level of the liquid in the bottle has reached the lower end of the tube 1, whereupon the flow of liquid into the bottle will automatically stop and the bottle may be quickly lowered so as to allow the head 7 of the vent tube to close the upper end of the discharge tube and positively cut off the flow of liquid.

In that form of the invention shown in Figs. Land 5 of the drawings, no vent tube is provided and the equivalent of the tube 1 is indicated by the numeral 19, the same being fitted at its upper end into a plug 20 corresponding to the plug 3. The numeral 21 indicates a ball valve designed to seat by gravity and close the upper end of the discharge tube 19 and this valve has secured within it the upper end of a wire stem 22, the lower portions of which stem are bent laterallyin opposite directions as at 23 and thence to extend vertically as at 24 and finally to extend laterally to form fingers 25 corresponding to the fingers of the lifting device in the previously described form of the invention. The operation of the apparatus shown in Figs. a and 5 will be obvious by reference to Fig. 4.

It will, of course, be understood that the vent tube (3 serves not only as a vent tube but also constitutes the stem of the head 7 which is in effect a valve and that, therefore, in a sense the tube 6 is the equivalent of the stem 22 in that form of the invention shown in Figs. 4 and 5 of the drawings.

It will further be understood, of course, that the barrel or other container from which the liquid is to be drawn is air-tight.

Having thus described the invention, what is claimed as new is:
